Answer:
x=27
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−5)=3x+7
Step 1: Simplify both sides of the equation.
4(x−5)=3x+7
(4)(x)+(4)(−5)=3x+7(Distribute)
4x+−20=3x+7
4x−20=3x+7
Step 2: Subtract 3x from both sides.
4x−20−3x=3x+7−3x
x−20=7
Step 3: Add 20 to both sides.
x−20+20=7+20
x=27
Answer:
x=27
Answer:8pts
Step-by-step explanation:
3x+x+20 = 180
4x = 180-20
4x = 160
x = 40
×+20+3x+2x+38+C=360
40+20+3×40+2×40+38+C=360
40+20+120+80+38+C=360
298+C=360
C=360-298
C =62°
