(1(1/5)) / (3/4)1(1/5) = 6/5therefore the question is(6/5) / (3/4)To divide a fraction, you simply swap the position of the numerator and denominator in the latter part of the example, and multiple the fr...

Multiply the first equation by 2 to obtain 2x+2y = 32,Then use the elimination technique and add the first equation into the second equation to get : 7x = 49 therefore divide by 7 to find x = 7 Sub this v...

We first expand the first set of brackets by multiplying each element of it by the second set of brackets so (x + 1)(2x + 3) = (x)(2x + 3) + (1)(2x + 3) = x(2x + 3) + (2x + 3). We can then expand out the ...

x=4, y=-2

Using the elimination technique:As we have -2y in both equations we can take the equations away from each other in order to eliminate -2y and create a new linear equation involving only x. this equation w...
