What is the solution to this system of linear equations? 2a – 3c = –6 a + 2c = 11
2a – 3c = –6 (equ. 1) a + 2c = 11 multiply -2 on both sides the result is: -2a - 4c = -22 (equ. 2) adding up equ. 1 and 2 the result is: -7c = -28 c = -28/-7 = 4 a = 11 - 2(4) = 11 - 8 = 3 The solution for the system 2a – 3c = –6 a + 2c = 11 is (3, 4)

2a – 3c = –6 (equ. 1)
a + 2c = 11 multiply -2 on both sides the result is:
-2a - 4c = -22 (equ. 2)
adding up equ. 1 and 2 the result is:
-7c = -28
c = -28/-7 = 4
a = 11 - 2(4) = 11 - 8 = 3
The solution for the system 2a – 3c = –6 a + 2c = 11 is (3, 4)

Questions asked by the same visitor
How many intersections are there of the graphs of the equations below? x + 5y = 6 3x + 30y = 36
Weegy: 3x^2+5y is a two-term polynomial. User: Using a stopwatch, Tyrone determines it takes him 58.2 minutes to travel 30 miles to work. The stopwatch measures to hundredths of a minute. Going by the accuracy of the stopwatch, which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work? (More)

x + 5y = 6 multiply 3 on both sides the result is:
3x + 15y = 18 (1)
3x + 30y = 36 (2)
subtracting 1 from 2 the result is:
15y = 18
y = 18/15 = 6/5
x = 6 - 5y = 6 - 5(6/5) = 6 - 6 = 0
The solution set for the equation is (0, 6/5) which is also their only intersection point.
