Find X: 1. 0.15x+6=51 2. −1.5x−9=0 3. 1.3x=54+x 4. −0.7x+2=65 5. (x−3)·2=30 6. 6x=−50 7. 42x=13+16x 8. 2x+9=−x 9. 5x−4y=24 Solve only the ones you know. Make sure its numbered though. I will mark brainliest!!!

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
