Question

Solve and check linear equations: 2x + 30 = 5​

Answer 1

Answer:

2x + 30 = 5

2x = -25

x = -12.5

Now, for checking we will substitute x.

2(-12.5) + 30 = 5

-25 + 30 = 5

5 = 5

LHS = RHS

Hence, checked.

Answer 2

Answer:

x=-25/2

Step-by-step explanation:

$2x + 30 = 5$

substract 30 from both side equation

$2x = 30 - 30 = 5 - 30$

$2x = - 25$

divide both sides of the equation

$2x = - 25$

$2x \div 2 = 25 \div 2$

$x = - 25 \div 2$

Thus the answer is -25/2
