Question

I will give 20 points and Brainliest for one question if someone gives an explanation and the answer!!!! PLs help me, and hurry:(

Answer 1

100+x+C=49+4x+c

51=3x

x=\frac{51}{3}

x=17

CHECK:

C=C

180-(100+x)=180-(4x+49)

180-(100+17)=180-(4(17)+49))

180-117=180-117

63=63  CHECKS

Answer 2

$100+x+C=49+4x+c$

$51=3x$

$x=\frac{51}{3}$

$x=17$

CHECK:

$C=C$

$180-(100+x)=180-(4x+49)$

$180-(100+17)=180-(4(17)+49))$

$180-117=180-117$

$63=63$  CHECKS
