12m-32=-80
12m=-80+32
12m=-48
m=-4
Answer:
2x + 4y = 12 and y = -1/2x + 3
Step-by-step explanation:
it is 12 because 12 - 7 is 5 the number 4 is the number multiplied by 3
65000x.135=8775
65000+8775=73775
So Bill earns $73,775 after the increase

The solution (-4,2) satisfies for the system of linear equations 3x + 13y = 14; 6x + 11y = -2
<u>Step-by-step explanation:</u>
Step 1:
Given detail is the solution of the equations (-4, 2) ie, x= - 4 and y = 2
This implies that this solution should satisfy the given linear equations.
Step 2:
Substitute values of x and y in the equations and verify whether the right hand side equals the left hand side.
System 1 Eq(1) ⇒ LHS = 3(-4) + 13 (2) = -12 + 26 = 14 = RHS
System 1 Eq(2) ⇒ LHS = 6(-4) + 11(2) = -24 + 22 = -2 = RHS
Therefore, the first system of linear equations satisfy the condition.
