Answer:
a. x = 7
b. x=12
Step-by-step explanation:
a. Let the number be x
According tot the statement
8x+4=60 (Equation Formed)
Solving
Subtract 4 from both sides
8x+4-4 = 60-4
8x = 56 (Divide both sides by 8 )
8x/8 = 56/8
x = 7
b. Let the number be x
According tot the statement
5/2*x - 7 =23 (Equation Formed)
Solving
Add 7 to both sides
5/2*x -7 +7 = 23 +7
5/2*x = 30 (Multiply both sides by 2 )
5/2x*2 = 30*2
5x = 60 (Divide both sides by 5 )
5x/5 = 60/5
x= 12
Hope it helped
