Question

(0.6х+1.85)-0.7=1.3х
помогите плиз

Answer 1

$(0.6x + 1.85) - 0.7 = 1.3x \ 0.6x + 1.85 - 0.7 = 1.3x \ 0.6x + 1.15 = 1.3x \ 0.6x + 1.15 - 1.15 = 1.3x - 1.15 \ 0.6x = 1.3x - 1.15 \ 0.6x - 1.3x = - 1.15 \ 0.7x = - 1.15 div - 0.7 \ x = frac{23}{14}$

Answer 2

(0,6х+1,85)-0,7=1,3х 0,6х+1,85-0,7=1,3х 0,6х-1,3х=0,7-1,85 -0,7х=-1,15 х=23/14=1 9/14
