Question

Solve the equation and check your result 3x+8 = 5x + 2​

Answer 1

Step-by-step explanation:

3x+8=5x+2

3x-5x=2-8

-2x=-6

2x=6

x=6/2

x=3

Answer 2

Answer

• x = 3

To Find

• The value of x.

Step By Step Explanation

Equation ⤵

3x + 8 = 5x + 2

So let's solve it !!

$\longmapsto\sf{3x + 8 = 5x + 2} \\ \\ \longmapsto\sf{8 - 2 = 5x - 3x}\\ \\ \longmapsto\sf {6 = 2x} \\ \\ \longmapsto\sf {\cfrac{ \cancel{6}}{ \cancel{2}} = x} \\ \\ \longmapsto\bf{ \red{3 = x}}$

Therefore, x = 3

Check

By substituting the value x = 3

L.H.S. ⤵

$\longmapsto\sf{3x + 8}\\ \\ \longmapsto\sf {3 \times 3 + 8} \\ \\ \longmapsto\sf{9 + 8} \\ \\ \longmapsto\sf{17}$

R.H.S.

$\longmapsto\sf{5x + 2} \\ \\ \longmapsto\sf {5 \times 3 + 2} \\ \\ \longmapsto\sf{15 + 2} \\ \\ \longmapsto\sf{17}$

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

Hence proved.
