Step-by-step explanation:

you move all the terms not containing a to the right sideof the equation.

add 4 to both sides of the equation

4a = 12+ 4

add 12 and 4

4a = 16

then divide by 4 and simplify

a = 4

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
