Step-by-step explanation:
We make "x" the subject of formula
2x = 11 + 5
(-5 changes to +5 because it's crossing over the equal to sign =)
2x = 16
(divide both sides by the coefficient of x)
2x ÷ 2 = 16 ÷ 2
X = 8
2. x /4 + 2 = 3
(we solve the Left Hand Side first by finding the LCM)
x/4 + 2
x + 8 = 3
‐---‐------
4
(cross multiply)
x + 8 = 4(3)
x + 8 = 12
x = 12 - 8
x = 4
3. 2(x - 7) = 3x + 10
(2 multiplies the entire bracket)
2x - 14 = 3x + 10
(collect like terms)
2x - 3x = 14 + 10
-x = 24
(multiply both sides by the negative sign "-")
x = -24
