STEP 1: Multiply second equation by -3.
After multiplying we have the following system:
3x+4y−3x+3y=8=−36
STEP 2: add the two equations together to eliminate x from the system.
7y=−28
STEP 3: find y
<u>y=−4</u>
<u></u>
STEP 4: substitute the value for y into the original equation to solve for x.
3x+4(−4)=8
<u>x=8</u>
Answer:
y = -7; x = 4
Step-by-step explanation:
x - 7y = 53
x = 7y + 53
-4x - 5y = 19
-4(7y + 53) - 5y = 19
-28y - 212 - 5y = 19
-33y = 231
-11y = 77
y = -7
x - 7(-7) = 53
x + 49 = 53
x = 4
