4-x=31
-4=-4
x=27
27 is the answer
The area of a trapezpid is 1/2h×(b1+b2)
Answer:
Step 1: Simplify both sides of the equation.
6(3x−5)−7x=25
(6)(3x)+(6)(−5)+−7x=25(Distribute)
18x+−30+−7x=25
(18x+−7x)+(−30)=25(Combine Like Terms)
11x+−30=25
11x−30=25
Step 2: Add 30 to both sides.
11x−30+30=25+30
11x=55
Step 3: Divide both sides by 11.
x=5
Step-by-step explanation:
Answer:
infinite solutions
Step-by-step explanation:
4x+4(3x+7) = 8(2x-3) +52
Distribute
4x+12x+28 = 16x-24+52
Combine like terms
16x+28 = 16x +28
Subtract 16x from each side
16x-16x+28 = 16x-16x +28
28=28
This is true, so there are infinite solutions
