Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(3x−6)−2x+1=25
(2)(3x)+(2)(−6)+−2x+1=25(Distribute)
6x+−12+−2x+1=25
(6x+−2x)+(−12+1)=25(Combine Like Terms)
4x+−11=25
4x−11=25
Step 2: Add 11 to both sides.
4x−11+11=25+11
4x=36
Step 3: Divide both sides by 4.
4x

Answer:
d)14
Step-by-step explanation:
use Pythagoras
a² = b² ,+ c²
50² = 48² + c²
2500 - 2304 = c²
196 = c²
√196 = c
c=14
Y = 3
