Question

solve the equation z=4(z+12)​

Answer 1

Answer:

Given :

Linear Equation => z=4(z+12)

What to find =( value of z)?

Solution:

$=>z = 4(z+ 12) \\=> z = 4z + 48 \\ => 4z + 48 - z =0 \\ =>3z + 48 = 0 \\ => 3z = - 48 \\ => z = \frac{ - 48}{3} \\ => z = - 16 \: \: answer$*Extra :

• Linear equation =An equation that can be written in the form

ax + b = c

[where a, b, and c are constants]

• A value, such that, when you replace the variable with it,it makes the equation true.

(the left side comes out equal to the right side)

For exercise :✈

Solve for the variable.

1. x - 5 = 2.
2. 5x=5
3. 10-3x=7
4. 5-x=-5
5. 4x-1=15
