Solve the equation. X × (1 − 49) = 56x + 79x = 211x-50% = 16 (x + 27) × 40% = 8
(1)x×(1-49)=56, 59x=56, 59x×95=56×95, x=32;(2)x+79x=2, 169x=2, 169x×916=2×916, x=98;(3)11x-50%=16 11x-50%+50%=16+50%, 11x=16.5, 11x÷11=16.5÷11, x=1.5;(4)(x+27)×40%=8,(x+27)×40%÷40%=8÷40%, x+27=20, x+27-27=20-27, x=1957.
Is 8x + 5x-2x = 11x an equation
This is an identity, not an equation
These two algebraic expressions are reduced to (1) 3x-8x-11x (2) 4ab-4a + ab-2a + 1
(1)3X-8X-11X
=-5x-11x
=-16x
(2)4ab-4a+ab-2a+1
=5ab-6a+1
Please solve the following equation 2x + 1.5x = 17.5
Original formula = 2x + 1.5x = 3.5x = 17.5
x=17.5/3.5=5
x=5
