<span>Solve the following system of equations by linear combination:
3x + 2y = 7
y = x – 4
</span><span>3x+2(x-4)=7 now solve for x
3x+2x-8=7
combine terms
5x-8=7
add 8
5x=15
divide by 5
x=3
plug that into the second equation
y=3-4
y=-1
solution

Answer:
Markia had 14 cookies.
Step-by-step explanation:
Let's represent the total amount of cookies as y.
We know that after she gave away 4 cookies and divided the remainder by 2, she had 5 cookies left.
This can represented as an equation.
= 5
To solve this equation we have to isolate the y.
= 5
Multiply both sides by 2 to isolate the y - 4: y - 4 = 10
Add 4 to both sides to isolate the y: y = 14
The total amount of cookies is 14.
Basketball 16+2=18 (2*8)+2
Baseball 40-5=36 (5*8)-4
Softball 18+6=24 ( (5*8)-4)/2 +6
8+18+36+24=86
8x + 2 > 34
-2 -2
8x > 32
8x (÷ 8) > 32 (÷ 8)
x > 4
so x can equal any number from 5 and infinity
Hope I helped !!! :)
