The statement is true. Use order of operations to solve:
4 (21) - 8 + 9 (21) - 1 =264
84 - 8+ 9 (21)-`1 = 264
84- 8 + 189 -1 = 264
76 + 189 - 1= 264
265- 1 = 264

4(21) - 8 + 9 (21) - 1 = 264
(84 - 8) + (189 - 1) = 264
76 + 188 = 264
264 = 264

4 x 21=84
9 x 21=189
84-8=76 +189= 265-1= 264

We follow BODMAS.
B stands for bracket, O for off , D- divison, M-multiplication, A-addition , S -subtraction. We do it in that order
4(21)-8+9(21)-1= 264
84-8 +189 -1=264
84-197-1=264
-378

This is not a question since there is no variable to solve for. If you want some help actually doing this to get 264 then you have to deal with order of operations. Just remember P.E.M.D.A.S. Parenthesis, exponents, multiplication, division, addition, subtraction. so in the problem it would be
4x21 = 84, 9x21 = 189, then you just have
84 - 8 + 189 - 1 = 264, which is simple arithmetic

You do the multiplication first.
84-8+189-1 = 264
76 + 188 = 264
264 = 264

4 x 21=84
9 x 21=189
84-8=76 +189= 265-1= 264
264 is your answer
