5x + 2y = 8, x + y = 4 If you want to solve the system of equations by addition, Multiply the second equation by -2 and add.

(x + y = 4) x (-2) =

(-2x - 2y = -8) + (5x + 2y = 8) =

3x = 0; x = 0/3; x = 0;

Plug x = 0:

5(0) + 2y = 8;

2y = 8; y = 8/2; y = 4

(x + y = 4) x (-2) =

(-2x - 2y = -8) + (5x + 2y = 8) =

3x = 0; x = 0/3; x = 0;

Plug x = 0:

5(0) + 2y = 8;

2y = 8; y = 8/2; y = 4

Simplify 2(x - 3) + 7(x + 2).
9x - 8
9x + 3
9x + 8 **Weegy:** 2(x - 3) + 7(x + 2) = 2x - 6 + 7x + 14 = 9x + 8 (More)

Find the value of 7 + 32 (-5 + 1) ÷ 2.
25
32
-11 **Weegy:**
7 + 32 (-5 + 1) ÷ 2
= 7 + 32(-4) ÷ 2
= 7 - 128 ÷ 2
= 7 - 64
= -57

Find two consecutive integers whose sum is 73.
Which of the following equations could be used to solve the problem?
**Weegy:**
x + (x + 1) = 73;
2x + 1 = 73;
2x = 73 - 1;
2x = 72;
x = 72/2;
x = 36, the next integer is 37.
36 + 37 = 73. The equation 2x + 1 = 73 could be used to solve the problem.
