Answer:
Heya here is your answer
Step-by-step explanation:
a) 3x = 18
x = 18/3
x = 6
b) 2x = 9
x = 4.5
x = 4 1/2 ( in Mixed fraction)
c) x/5 = 7
x = 7 x 5
x = 35
d) x/2 = 6.5
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
X/2 = 6.5 // - 6.5
X/2-6.5 = 0
1/2 X -6.5 = 0 + 6.5
1/2X = 6.5 : 1/2
X = 6.5/1/2
X = 13
Hope this answer satisfies you
