Answer:

a)7

b)x=6

Step-by-step explanation:

Answer:

z = 4, x = 6

Step-by-step explanation:

(a)

[tex]\frac{5z+1}{3}[/tex] = 7 ( multiply both sides by 3 to clear the fraction )

5z + 1 = 21 ( subtract 1 from both sides )

5z = 20 ( divide both sides by 5 )

z = 4

(b)

[tex]\frac{5x}{3}[/tex] + 3 = x + 7 ( multiply through by 3 to clear the fraction )

5x + 9 = 3x + 21 ( subtract 3x from both sides )

2x + 9 = 21 ( subtract 9 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6
