= 6a(4b - 7x) - 5(4b - 7x)
= (4b - 7x)(6a - 5)

To factorise the expression (70a - 20b - 10c), first identify the greatest common factor (GCF) of the coefficients, which is 10. Then, factor out 10 from the entire expression: [ 70a - 20b - 10c = 10(7a - 2b - c). ] Thus, the factorised form is (10(7a - 2b - c)).

Write down both equations (I'll label them (1) and (2)):(1) a = 3b - 4(2) a + b = 16Pass b to the left side of the equation (1):(1) a - 3b = -4(2) a + b = 16Multiply (1) by -1:(1) -a + 3b = 4(2) a + b = 16Add down both equations:-a + 3b + a + b = 4 + 164b = 20b = 5Replace b in (2):a + 5 = 16a = 11
