Answer:
22x + 24
Step-by-step explanation:
7x+9+7x+9+4x+3+4x+3
11x + 18 + 11x + 6
Mark brainliest please!
Take the numbers to one side
<span>-6f+13=2f-11
-6f - 2f = -11 - 13
-8f = -24
f = 3</span>
3(x + 2) + 4(x - 5) = 10
Use the distributive property:
3x + 6 + 4x - 20 = 10
Combine like terms:
7x -14 = 10
Add 14 to both sides:
7x = 24
Divide both sides by 7:
x = 24/7
