1. 189 x 4 + 6 =​

try this. the error is that sariah was combining a constant (4.5) with a variable with a coefficient, thus getting an inaccurate answer.

this is also assuming that you meant to put an equal sign before the 4.5 + x 35 x

to solve this problem, the strategy used is just to solve it yourself and find the correct answer by combining like terms.

hope this !
