-
Equation 1.2(5x-2)=8-(10.4-6x)
- Equation 2sin2x–√2·cosx=√2·sinx
- Equation +x^4-6*x^3-7*x^2+18=0
- Express {x} in terms of y where:
- 14*x-16*y=14
- -12*x+3*y=-9
- 9*x-18*y=6
- 4*x+13*y=13
-
Identical expressions
- one . two (5x- two)= eight -(ten . four -6x)
- 1.2(5x minus 2) equally 8 minus (10.4 minus 6x)
- one . two (5x minus two) equally eight minus (ten . four minus 6x)
- 1.25x-2=8-10.4-6x
-
Similar expressions
- 1.2(5x+2)=8-(10.4-6x)
- 1.2(5x-2)=8-(10.4+6x)
