3.option a (-8,2)
4.option b (5,4)
X = 4
First take 12x off both sides, so -7x=-28
The negatives cancel out, so 7x=28
Not find the hcf and divide by that.
110x4=440 beats in 4 minutes
3 times 8 is 24 and adding 7 is 31 so 31/1 divided by 19/1
U must flip the 19/1 to 1/19 and make it multiplication sign
31/1 times 1/19 is 31/19 or 1.63157
