Answer:
x=1.875
Step 1: you need to multiply the brackets.
-2(5x+8) = -10x-16
-10x-16=14+6x
Step 2: you want to put the x on one side, so take away 6 x from both sides
-10x-6x=-16x, 6x-6x=0
-16x-16=14
Step 3: add 16 to both sides so the whole numbers are on one side
-16+16=0, 14+16=30
-16x=30
Step 4: finally, divide the whole by the number of x, so 16
x=1.875
If you need to round it to a significant figure:
1 Sf: x=1.9
2Sf: x=1.78
3 Sf: the final answer only has three figures after the decimal.
