1) Form new equations by carrying out the
action (given in brackets) on both sides
of the equation.
(i) 2x + 3 = 13 (Multiply by 2)
(ii) 3y - 3 = 21 (Add 5)
(iii) 5x + 14 = 24 (Subtract 6)
(iv) 10y + 6 = 36 (Divide by 2)
(v) 5+ 4x = 21 (Multiply by 3)
(vi) 8 + 7x=29 (Subtract 4)

Answer:
(i) x = 5
(i) x = 5(ii) y = 8
(i) x = 5(ii) y = 8(iii) x = 2
(i) x = 5(ii) y = 8(iii) x = 2(iv) y = 3
(i) x = 5(ii) y = 8(iii) x = 2(iv) y = 3(v) x = 4
(i) x = 5(ii) y = 8(iii) x = 2(iv) y = 3(v) x = 4(vi) x = 3
Step-by-step explanation:
(i) 2x + 3 = 13
2x = 13 – 3
2x = 10
x = 10/2
x = 5
(ii) 3y – 3 = 21
3y = 21 + 3
3y = 24
y = 24/3
y = 8
(iii) 5x + 14 = 24
5x = 24 – 14
5x = 10
x = 10/5
x = 2
(iv) 10y + 6 = 36
10y = 36 – 6
10y = 30
y = 30/10
y = 3
(v) 5 + 4x = 21
4x = 21 – 5
4x = 16
x = 16/4
x = 4
(vi) 8 + 7x = 29
7x = 29 – 8
7x = 21
x = 21/7
x = 3
I hope that it would have helped you, Thanks.
