Weegy: 6x+18y=6(mul by 3) 6x+4y=20(mul by 2).So sub the 2 eq from 1.Hence 14y=-14.So y=-1 and hence 2x=2+6.So x=4.

Given the function f(x) = - 2x , find the value of f(–1).
Weegy: f(-1) = (-1)^2 - 2(-1) = 3 f(1) = 1^2 - 2(1) = -1 (More)

When f(x) = - 2x , the value of f(–1) is 2.
f(-1) = -2*(-1) = 2.

In the form, y = mx + b, m stands for the slope and b stands for the y-intercept; therefore, in the equation y = 2x + 1,
Slope: 2
y-intercept: 1

If the system of equations given below is solved using the substitution method, what is the equation that results from solving the second equation for y, and substituting into the first equation? 3x - 2y = 7 x - y = 5
Weegy: (3x-2) squared is 9x^2 - 12x + 4. (More)

3x - 2y = 7 (equ. 1)
x - y = 5 rearranging the equation we get:
y = x - 5 (equ. 2)
using equation 2 to substitute y in the equation 1 the result is
3x - 2(x - 5) = 7
the equation that results from solving the second equation for y, and substituting into the first equation is 3x - 2(x - 5) = 7

3x - 2y = 7 and x - y = 5, The equation that results from solving the second equation for y, and substituting into the first equation is: 3x - 2x + 10 = 7.

3x - 2y = 7 (equation 1)
x - y = 5 rearranging the equation we get: y = x - 5 (equation 2)
using equation 2 to substitute y in the equation 1:
3x - 2(x - 5) = 7
or 3x - 2x + 10 = 7
