Question

solve for x and verify your answer.

i) 3x + 4 = 7

Answer 1

x = 7/3 -3

now solve it i hope this is helpful

Answer 2

$\fbox\blue{A}\fbox\pink{N}\fbox\red{S}\fbox\green{W}\fbox\orange{E}\fbox\purple{R}$

3x + 4 = 7

=> 3x = 7 - 4

=> 3x = 3

=> x = $\frac{3}{3}$

=> x = $\frac{\cancel{3}}{\cancel{3}}$

∴ x = 1

Verification :-

Substituting the value of 'x' in the above equation

3x + 4 = 7

=> (3 × 1) + 4 = 7

=> 3 + 4 = 7

=> 7 = 7

Since L.H.S = R.H.S.

∴ Hence verified
