Question

Solve: 7+2a+1-3a=5a Write the STEPS or your answer will be reported

Answer 1

Answer:mark as brainliast plzzz

Step-by-step explanation:

7+2a+1-3a=5a, so first we will make sure that variable will be in one side so we send -3a and 2a in rhs and will become 7+1=5a+3a-2a (sign change)

By adding and subtracting 8=6a

Sending 6 into rhs so it will be in divide

8/6=a, by simplifying, 4/3=a

Answer 2

$\sf\:\implies 7 + 2a + 1 - 3a = 5a$

$\sf\:\implies 8 - a = 5a$

$\sf\:\implies 8 = 5a - a$

$\sf\:\implies 6a = 8$

$\sf\:\implies a = \frac{8}{6}$

$\sf\:\implies a = \frac{4}{3}$

★ Verification,

$\sf\:\implies 7 + 2[ \frac{4}{3} ] + 1 - 3 [ \frac{4}{3} ] = 5[ \frac{4}{3} ]$

$\sf\:\implies 7 + \frac{8}{3} + 1 - 4 = \frac{20}{3}$

$\sf\:\implies\frac{21 + 8 + 3 - 12}{3} = \frac{20}{3}$

$\sf\:\implies\frac{20}{3} = \frac{20}{3}$

Therefore,LHS = RHS.

Hence,it was verified.
