I dont need answers just an explaination how to solve these will give brailiest
ohaa [14]

Step-by-step explanation:

first you have to take all similar variable on the same side of the equation and the constants on the other side then solve the question .

example : -12x + 9 = -15x

-12x +15x = -9

3 x = -3

X = -3/3= -1

x = -1

like this you can solve all the other equation ..

<em>Hope </em><em>this </em><em>will </em><em>be</em><em> helpful</em><em> to</em><em> you</em><em> </em><em>.</em><em>.</em>

<em>plz </em><em>mark</em><em> my</em><em> answer</em><em> as</em><em> brainlist</em><em> </em><em>if </em><em>you</em><em> </em><em>find </em><em>it </em><em>useful</em><em>.</em><em>.</em>
