Step 1: you need to multiply the brackets.
-2(5x+8) = -10x-16
Step 2: you want to put the x on one side, so take away 6 x from both sides
Step 3: add 16 to both sides so the whole numbers are on one side
Step 4: finally, divide the whole by the number of x, so 16
If you need to round it to a significant figure:
1 Sf: x=1.9
3 Sf: the final answer only has three figures after the decimal.
1. Distribute the -2. multiply-2 with 5x and 8. it will be -10x-16=14+6x. For me, i make small numbers negative or positive than big ones. Add 16 to both sides. it will be -10x=30+6x. Subtract 6x. -10x-6x=-16x. Divide both sides by 16. x=30/16= 1 and 14/16
