Seven subtracted from the product of a number and -4 is -59, let me translate it.
[tex]-4x-7=-59[/tex]Let me solve it now (Next).
[tex]\rightarrow4x+7\text{ = 59}\rightarrow x=13[/tex]The sum of two-sevenths of a number and 3 is 9
[tex]\frac{2x}{7}+3=9[/tex]This is the translation, let me solve it next.
[tex]\frac{2x}{7}=6\rightarrow x\text{ = }\frac{42}{2}=21[/tex][tex]x^2-14=50\rightarrow x\text{ = 6}[/tex][tex]\frac{40x}{100}-10\text{ =-4}[/tex][tex]\frac{40x}{100}=6\rightarrow x\text{ = }\frac{600}{40}=15[/tex]The quotient of a number increased by 4 and -3 is 15
[tex]\frac{x}{4}-3=15\rightarrow x=72[/tex]
